We're dividing 35095439 by 644 
We want to divide 35095439 by 644.

Going ahead to step 1:
3 divided by 644 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 644

On to step 2:
When dividing 35 by 644, we get 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 644

Going ahead to step 3:
When dividing 350 by 644, we get 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 350 after subtracting 0 from 350.
Fetch the next digit (9) from the dividend, attach it to 350 and continue: 3509 / 644

On to step 4:
644 goes into 3509 5 times with a remainder of 289.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3220 from 3509 and we're left with 289.
Fetch the next digit (5) from the dividend, attach it to 289 and continue: 2895 / 644

On to step 5:
The number 644 fits into 2895 4 times, leaving a remainder of 319.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Deduct 2576 from 2895 and we're left with 319.
Include the next digit (4) from the dividend after 319, then repeat: 3194 / 644

On to step 6:
When dividing 3194 by 644, we get 4 with a remainder of 618.
Record the quotient 4 as the next digit in the result. 
Result so far: 544.0
If we subtract 2576 from 3194, we get 618.
Grab the next digit (3) from the dividend, add it to 618, then carry on: 6183 / 644

Step 7:
The number 644 fits into 6183 9 times, leaving a remainder of 387.
Put 9 as the next digit of the answer. 
Result so far: 5449.0
Deduct 5796 from 6183 and we're left with 387.
Bring next digit (9) of the dividend behind the 387 and repeat the process: 3879 / 644

Moving on to step 8:
3879 divided by 644 is 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 54496.0
Deduct 3864 from 3879 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 644, we get 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 54496.0
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
644 goes into 1500 2 times with a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 54496.02
The remainder is 212 after subtracting 1288 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 11:
644 can be fit into 2120 3 times, resulting in a remainder of 188.
Use 3 as the next digit of our solution. 
Result so far: 54496.023
Deduct 1932 from 2120 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 12:
The number 644 fits into 1880 2 times, leaving a remainder of 592.
Use 2 as the next digit of our solution. 
Result so far: 54496.0232
Subtract 1288 from 1880 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 13:
5920 divided by 644 is 9 with a remainder of 124.
The number 9 becomes the next digit in our result. 
Result so far: 54496.02329
Subtract 5796 from 5920 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 14:
When dividing 1240 by 644, we get 1 with a remainder of 596.
The number 1 becomes the next digit in our result. 
Result so far: 54496.023291
If we subtract 644 from 1240, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 15:
The number 644 fits into 5960 9 times, leaving a remainder of 164.
Put 9 as the next digit of the answer. 
Result so far: 54496.0232919
Subtract 5796 from 5960 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 16:
644 goes into 1640 2 times with a remainder of 352.
Use 2 as the next digit of our solution. 
Result so far: 54496.02329192
If we take 1288 away from 1640, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 54496.02329192 and a remainder of 3.52e-07.
